The venturi meter is the favoured device for wet gas flow metering. The simplicity of no moving parts makes the venturi meter maintenance free and the dependability allows it to be used in applications with higher turndown rates and/or lower pressures drops.
Wet gas flow metering is a major challenge to the natural gas production industry and potential applications. Many natural gas reserves that initially produced dry gas are becoming wet natural gas producers as the conditions in the reservoir change with age and the natural gas is depleted.
Venturi meters can be manufactured in duplex stainless steel to withstand corrosion as a result of the acidity of the wet gas.
